AMD Radeon Pro Vega 56 vs AMD Radeon RX 6650M Comparison

Head-to-Head Benchmarks

The direct comparison between the AMD Radeon RX 6650M and the AMD Radeon Pro Vega 56 shows a clear winner in both shared benchmark tests. In OpenCL, the RX 6650M scores 65,800 against the Pro Vega 56's 61,930, a 6.2% advantage. This is a meaningful gap, though not a dominant one; it suggests the newer architecture extracts more real-world compute throughput from its resources. The Vulkan result widens the margin considerably: the RX 6650M posts 77,735 versus 66,004 for the Pro Vega 56, a 17.8% lead. That is a substantial difference and points to significant efficiency gains in API-level performance.

Context from the nearest-rival data reinforces the picture. The RX 6650M's average benchmark score is 71,768, placing it in the 91st percentile of all GPUs. Its closest rival, the NVIDIA TITAN X Pascal, averages 72,098, a mere 0.5% higher; the AMD Radeon Pro Vega 64 sits at 72,379, 0.8% above. The RX 6650M also edges out the AMD Radeon RX 6600 LE (70,829) by 1.3%, while trailing the AMD Radeon Vega Frontier Edition (73,370) by 2.2%. The Pro Vega 56, by contrast, averages 63,693, landing in the 89th percentile. Its nearest rival is the AMD Radeon RX 7600M at 63,775, just 0.1% higher; the AMD Radeon RX 9060 XT LP (63,830) and NVIDIA CMP 30HX (63,842) are each 0.2% ahead, and the AMD Radeon Pro WX 9100 (64,212) leads by 0.8%. The head-to-head delta of 17.8% in Vulkan is far larger than any gap between the RX 6650M and its own rivals, indicating that the Pro Vega 56's weakness in modern APIs is structural, not marginal.

The OpenCL result is more nuanced. A 6.2% lead is respectable but not overwhelming, and it aligns with the close cluster around the Pro Vega 56's average score in that benchmark's nearest rivals. The data suggests that in compute-heavy OpenCL workloads, the older GCN architecture can still hold its own to a degree. However, the Vulkan test tells a different story: the 17.8% gap shows that the RDNA 2.0 design extracts far more from the same API, likely due to architectural improvements in command processing and shader efficiency. The wins tally is 2-0 in favor of the RX 6650M, with no benchmark where the Pro Vega 56 takes the lead.

Where Each One Wins

Looking at the benchmark distribution, the RX 6650M wins in every measured category. There is no test in the data where the Pro Vega 56 outperforms it. That said, the magnitude of the wins varies by workload type, which informs use-case recommendations.

The RX 6650M's Vulkan dominance (17.8% over the Pro Vega 56) makes it the clear choice for modern game engines and Vulkan-based applications. The 77,735 score is its strongest absolute result, and given that Vulkan is the foundation for most contemporary cross-platform titles, this is a decisive advantage. The OpenCL win (6.2%) is smaller but still consistent, covering compute workloads like rendering, physics simulation, and general-purpose GPU tasks.

The Pro Vega 56 has no winning benchmark in this dataset. Its highest score is 66,004 in Vulkan, which is still 11,731 points below the RX 6650M's Vulkan result. In OpenCL, it scores 61,930, which is 3,870 points below the RX 6650M's 65,800. The only benchmark unique to the Pro Vega 56 is Metal (63,145), which the RX 6650M was not tested on; this result is lower than the RX 6650M's OpenCL score and roughly comparable to its own OpenCL figure. Therefore, for any user prioritizing raw performance in the shared test suite, the RX 6650M is unequivocally the stronger part.

In terms of percentile ranking, the RX 6650M sits at the 91st percentile versus the Pro Vega 56's 89th. That two-percentile gap reflects the average score difference of 71,768 versus 63,693, an 11.3% overall advantage. For workloads that rely on OpenCL and Vulkan, the RX 6650M is the superior option. The Pro Vega 56 might still be relevant for legacy compute stacks or Metal-specific environments, but the data does not show any scenario where it wins a shared benchmark.

Architecture Differences

The two GPUs come from different architectural generations and process nodes. The RX 6650M is built on RDNA 2.0, using the Navi 23 chip, fabricated on a 7 nm process at TSMC. It packs 11,060 million transistors into a 237 mm² die, yielding a transistor density of 46.7 million per mm². The Pro Vega 56 uses GCN 5.0, built on the Vega 10 chip, fabricated on a 14 nm process at GlobalFoundries. It contains 12,500 million transistors across a much larger 495 mm² die, with a transistor density of 25.3 million per mm². The RX 6650M is roughly half the die size but achieves a density that is 84% higher, a direct consequence of the newer node.

Clock speeds differ substantially. The RX 6650M has a base clock of 2068 MHz, a game clock of 2222 MHz, and a boost clock of 2416 MHz. The Pro Vega 56 operates at a base of 1138 MHz and a boost of 1250 MHz. The RX 6650M's boost clock is nearly double the Pro Vega 56's, which explains how a smaller chip can deliver comparable or better performance in many scenarios.

Memory configurations diverge sharply. The RX 6650M uses 8 GB of GDDR6 on a 128-bit bus, delivering 224.0 GB/s of bandwidth at 14 Gbps effective. The Pro Vega 56 uses 8 GB of HBM2 on a 2048-bit bus, delivering 402.4 GB/s at 1572 Mbps effective. The Pro Vega 56 has 79.6% more memory bandwidth, which is a significant advantage for memory-bound workloads. However, the RX 6650M's higher clocks and architectural efficiency compensate in the benchmark results.

Compute resources also differ. The RX 6650M has 1792 shading units, 112 texture mapping units, 64 ROPs, and 28 ray accelerators. The Pro Vega 56 has 3584 shading units, 224 TMUs, and 64 ROPs, but no dedicated ray accelerators. Despite having exactly twice the shading units and TMUs, the Pro Vega 56 only achieves slightly higher FP32 throughput: 8.960 TFLOPS versus 8.659 TFLOPS for the RX 6650M. FP16 performance is similarly close, at 17.92 TFLOPS versus 17.32 TFLOPS. The RX 6650M's pixel rate is 154.6 GPixel/s versus 80.00 GPixel/s for the Pro Vega 56, a 93% advantage; its texture rate is 270.6 GTexel/s versus 280.0 GTexel/s, a 3.4% deficit.

Power consumption is also a major differentiator. The RX 6650M has a TDP of 120 W, while the Pro Vega 56 draws 210 W. That is a 75% higher power draw for the older card. Both are listed as IGP (integrated graphics processor) with no power connectors, meaning they are designed for system integration rather than discrete installation. The RX 6650M uses PCIe 4.0 x8, while the Pro Vega 56 uses PCIe 3.0 x16.

API support favors the newer card: the RX 6650M supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the Pro Vega 56 supports DirectX 12 (12_1) and Vulkan 1.3. Both support OpenGL 4.6. The RX 6650M's display outputs are listed as "Portable Device Dependent," reflecting its mobile design, while the Pro Vega 56 has 1x HDMI 2.0b and 3x DisplayPort 1.4a.

The Verdict

The data is unambiguous: the AMD Radeon RX 6650M is the superior GPU in every shared benchmark. It leads by 6.2% in OpenCL and by 17.8% in Vulkan, and its average score of 71,768 is 11.3% higher than the Pro Vega 56's 63,693. The percentile ranking confirms this, with the RX 6650M at the 91st percentile versus the 89th for the Pro Vega 56.

The architectural advantages are clear. The RX 6650M's RDNA 2.0 architecture on a 7 nm process delivers higher clocks (2416 MHz boost versus 1250 MHz), a smaller die (237 mm² versus 495 mm²), and lower power draw (120 W versus 210 W) while still achieving comparable or better compute throughput. The Pro Vega 56's larger memory bandwidth (402.4 GB/s versus 224.0 GB/s) and double shading units do not translate into benchmark wins, indicating that raw resource counts are less important than architectural efficiency in modern APIs.

For users selecting between these two, the choice depends on the workload. If the requirement is OpenCL or Vulkan performance, the RX 6650M is the clear pick. Its 17.8% Vulkan lead makes it particularly strong for modern gaming and compute applications. The Pro Vega 56, with no winning benchmark and higher power consumption, appears to be a weaker option in every measured category. Its only potential advantage is in Metal-specific environments, where it scores 63,145, but even that result is below the RX 6650M's OpenCL score. The RX 6650M is the better choice for virtually every use case represented in this data.
